[PATCH] RISC-V: Add .insn support

[Andrew Waterman]

Hi Kito,

Thanks for contributing this patch.  I did not thoroughly review the
code, but I like the approach.  Jim or Palmer will probably follow up
with additional comments.

I noticed a typo: major opcode 0x6f should be named JAL, not JAR.
(The test case and the documentation also have this typo.)
